PU RIFIER FOR STEAM-BOILERS.

SPECIFICATION forming part of Letters Patent No. 458,836, datedSeptember 1, 1891.

Application filed April 28, 1891. Serial No. 390,741- (No model.)

To all whom it may concern.-

Be it known that JAMES E. KINTZEL, deceased, late a citizen of theUnited States, and a resident of La Junta, in the county of Otero andState of Colorado, did in his life-time invent certain new and usefulImprovements in Purifiers for Steam-Boilers; and I do declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to the letters and figures of reference marked thereon, which form apart of this specification.

This invention relates to purifiers for steamboilers; and it has for itsobject to remove the scum from the boiling water, so as to prevent theimpurities therein from settling upon the back flue-sheet and theflue-pipes, whereby all tendency to incrustation or scaling will beeffectually prevented.

A further object is to provide means for automatically removing allmineral or earthy deposits which may accumulate in the mudring.

The invention will first be described in connection with theaccompanying drawings, and then pointed out in the claim.

In the drawings, Figure l is an elevation of a locomotive-boiler, partlyin section, showing the position occupied by the improved purifier. thesectiorrline being taken immediatelyback of the back fiue-sheet, showingthe purifier and also the mechanism for removing the mud from themud-ring. Fig. 3 is a detached view of the purifier removed from theboiler.

Referring to the drawings, A designates the boiler, and B the backflue-sheet. Arranged within the boiler at a point adjacent to the backflue-sheet and resting upon the fluepipes C is the purifier orskimmer-tube, which consists of a closed-end tube or cylinder I), theupper surface of which is provided with a number of perforations 1.Along each side of these perforations are secured a series of knees 2,which serve as guides for a slide E, which is also provided with aseries of per- Fig. 2 is a perspective view in section,

forations 3, adapted when the slide is moved to the proper position toregister with the perforations in the cylinder. The outer end of theslide extends through the boiler-shell and is provided with a handle 4..

F designates a discharge-pipe, which connects with the cylinder at ornear the center of one side thereof. This pipe is curved outward andthen downward and extends to within a short distance of the ground.

G designates a valve carried by the discharge-pipe. To the handle 5 ofthe valve is attached a rod 6, which extends Within the cab, so as toenable the engineer to open or close the valve at will.

II designates two siphon-pipes, which are tapped into the discharge-pipeand extend to the sides of the fire-box I and pass down between the saidbOX and the boiler-shell .l. The lower ends of the pipes are bentbackward, so as to lie in the mud-ring K, and these horizontal portions7 are perforated, as at 8.

In carrying the invention into effect the cylinder is so arranged in theboiler that its upper surface will be slightly below the surface of thewater, and being located near the flue-sheet, at which point there isthe greatest accumulation of scum, owing to the intense heat, it followsthat as soon as the slide is moved to bring its perforations in registerwith those in the cylinder the scum will escape through the escape-pipeto the ground. As long as the purifier is in operation the siphon-pipesH will remain inoperative; but as soon as the slide E is moved so as toclose the openings in the cylinder the steam-pressure in the boiler willcause these pipes to siphon or suck the mud or other accumulation fromthe mud-ring and discharge it through the pipe F to the ground. WVhen itis not necessary to use either the purifier or the siphonpipes, thevalve G is closed, thus rendering the device inoperative.

I am aware that heretofore devices for re moving scum have been used inboilers; but I am not aware that previous to this invention askimmer-tube has been placed transversely of the boiler and adjacent tothe back fluesheet. By arranging the skimmer-tube as just stated a verysuperior result is achieved as compared with the arrangement of askimming device longitudinally of the boiler or transversely at a pointremote from the back fluesheet. It is well known that the greatestintensity of heat is at the back flue-sheet, and that consequently thegreatest amount of scum is generated there. Now should the skimmer-tubebe arranged longitudinally of the boiler it would serve to gather thescum in its immediate vicinity only, and consequently its operation tothat extent would be defective. Again, should a skimming device beplaced transversely of the boiler, but at a point remote from the backflue-sheet, the scum back of the skimmer would find its way to thesteam-dome and there clog the throttle. These faults are effectuallyremedied by this invention, for as the skimmer-tube is arrangedtransversely of the boiler at its rear end no scum can reach the domeand dry-pipe without passing over the skimmer, and in doing so it willbe drawn off.

WVhat is claimed as the invention of the said JAMES E. KINTZEL is- In asteam-boiler, the eombination, with the back flue-sheet and themud-ring, of a closedend cylinder arranged adjacent to and parallel withthe flue-sheet and having a series of perforations extending alongitsupper side, a slide arranged on top of the cylinder and havingperforations adapted to be movedinto and out of register with theperforations in the cylinder, a valved discharge-pipe connecting withthe cylinder and extending through the boiler-shell, and twosiphon-pipes connecting with the escape-pipe near its point ofattachment with the said cylinder, said pipes extendingaround thefire-box and into the mud-ring, the lower end of each of the pipes beingbent so as to extend within the mud-ring and perforated in the bentportions.

In testimony whereof I affix my signatu rein the presence of twowitnesses.
